AMA/AMBA MA Motion Sensors, Panasonic
The AMA/AMBA series of MA motion sensors are designed to detect humans using infrared rays - irrespective of reflection, material or cleanliness. Other advantages of the AMBA/AMA series include thinner versions for easier device installlation, built-in oscillation for certain versions, the sensors can be used over a wide range of supply voltages and each sensor can be used adjacent to other sensors to reduce beam frequency interference. The motion sensors are suited to applications that require automatic features such as toilets, doors, lighting and game displays.
